Rhizon soil moisture sampler we offer is very easy to use. This sampler is part of the core technology is the sampling head with a porous membrane, automatic wet, it does not produce adsorption, but also to avoid cross-contamination. The sampler is placed in a horizontal wet moist soil. During insertion water as a lubricant. It is very small due to the interference of the soil, the soil can be quickly returned to normal, so the sample can maintain good contact with the soil. Standard Rhizon soil moisture samplers should pass through undisturbed soil column walls and pots. After extraction with a syringe or a vacuum tube, the sampler can be placed under vacuum sampling. Sampler consists of three parts: the front end as a white porous membrane composed of a hydrophilic sampling head (Porous part, a diameter of 2.5mm, an average pore size 0.15um, there are reinforcing filaments, there are two sizes 5cm and 10cm), no middle color transparent extension tube (Extension Tube, made of PE / PVC pipe, the length can be customized according to needs), the end of the joint (Male luer lock, luer positive for connecting tube; Female luer lock connector for connecting the negative Ruhr syringe). Rhizosphere sampler provided are the following types: SMS, MOM, CSS, Flex, MacroRhizon, MicroRhizon and Rhizon Box, in addition there is a RhizonCera, sampling head for the ceramic material. Main purpose: Rhizon soil moisture samplers are very suitable for pots, soil column studies (CSS used for undisturbed soils, sediments, such as acquisition, Macro Rhizon field for field trials, MicroRhizon for agar or RhizonBox). If you need to work with a soil sample several soil solution can also be used Rhizon soil moisture sampler. Thus the following study: soluble plant nutrients such as nitrate uptake root exudates as allelochemicals in soil studies soluble soluble metal content in soil salinity accumulation transmission environmental (water lake sediments) Performance advantages: Original bit extraction, destruction of soil hydraulic properties of the minimum dead volume small, less than 0.5 ml of ion exchange capacity of the smallest (less than soil) PH value after sampling the same low price RHIZON CSS for in situ direct sampling, collecting hard soil and undisturbed sedimentary thereof. 19.21.23 sampling head length 5cm, glass fiber reinforced wire, PVC / PE extension tube length 12cm, positive connector can be connected to a vacuum; 10 per pack. 19.21.23F sampling head length 5cm, glass fiber reinforced wire, PVC / PE extension tube length 12cm, female connectors can be connected to a syringe; 10 per pack. 19.21.24 sampling head length 10cm, glass fiber reinforced wire, PVC / PE extension tube length 12cm, positive connector can be connected to a vacuum; 10 per pack. 19.21.24F sampling head length 10cm, glass fiber reinforced wire, PVC / PE extension tube length 12cm, female connectors can be connected to a syringe; 10 per pack.
